Variational Color Shift and Auto-Encoder Based on Large Separable Kernel Attention for Enhanced Text CAPTCHA Vulnerability Assessment

Text CAPTCHAs are crucial security measures deployed on global websites to deter unauthorized intrusions. The presence of anti-attack features incorporated into text CAPTCHAs limits the effectiveness of evaluating them, despite CAPTCHA recognition being an effective method for assessing their security. This study introduces a novel color augmentation technique called Variational Color Shift (VCS) to boost the recognition accuracy of different networks. VCS generates a color shift of every input image and then resamples the image within that range to generate a new image, thus expanding the number of samples of the original dataset to improve training effectiveness. In contrast to Random Color Shift (RCS), which treats the color offsets as hyperparameters, VCS estimates color shifts by reparametrizing the points sampled from the uniform distribution using predicted offsets according to every image, which makes the color shifts learnable. To better balance the computation and performance, we also propose two variants of VCS: Sim-VCS and Dilated-VCS. In addition, to solve the overfitting problem caused by disturbances in text CAPTCHAs, we propose an Auto-Encoder (AE) based on Large Separable Kernel Attention (AE-LSKA) to replace the convolutional module with large kernels in the text CAPTCHA recognizer. This new module employs an AE to compress the interference while expanding the receptive field using Large Separable Kernel Attention (LSKA), reducing the impact of local interference on the model training and improving the overall perception of characters. The experimental results show that the recognition accuracy of the model after integrating the AE-LSKA module is improved by at least 15 percentage points on both M-CAPTCHA and P-CAPTCHA datasets. In addition, experimental results demonstrate that color augmentation using VCS is more effective in enhancing recognition, which has higher accuracy compared to RCS and PCA Color Shift (PCA-CS).

Securing the Web: Analysis of HTTP Security Headers in Popular Global Websites

Securing the Web: Analysis of HTTP Security Headers in Popular Global Websites

Web use remains highly regional even in the age of global platform monopolies.

The Internet, since its inception, has been imagined as a technology that enables information to overcome barriers of language and geography. As a handful of social media platforms now dominate globally, removing most barriers of distribution; this has created unprecedented opportunities for content to gain worldwide traction, regardless of its country of origin. Yet historically with few exceptions, people generally consume content that is from or for their region. Has the Internet or social media really altered this trait? Analyzing the extent of similarities between a hundred countries' web use patterns simultaneously across their most popular websites, and country specific trends from YouTube and Twitter respectively, we find that countries which share borders or where people speak the same languages have the most similar web use patterns. Global social media usage on both YouTube and Twitter is even more heterogeneous and driven to a larger extent by language and geography than global website traffic. Neither does high prevalence of English language speakers in the two countries, nor does one of them being the United States contributes substantially to web use similarity. Global web use remains highly regional. The technical affordances of the Internet alone are thus insufficient to render a cosmopolitan world.

RENEWABLE ENERGIES IN THE SETTLEMENTS (A STEP TOWARD A CLEAN CITY)

As a result of the energy crisis of fossil fuel in the world, and pollution that comes from using these types of fuels, humans need to find clean and affordable energy to survive, impelling communities which produce their energy to carry out new initiatives. The use of wind, water, earth, solar and other clean energy has become possible, and finally, the world is on a path that requires new research in this field. Between the urban and social elements, per capita energy in the housing sector is allocated the highest consumption in the world, and this sector has the greatest amount of energy consumption in Iran as well. Researchers are presenting new solutions in addition to the usage of technology in the production of renewable energies, making closer to reality the reproducible ideas about using parts of buildings and natural forces around the buildings. This study is an attempt to explore the surrounding natural forces and materials that are used in construction, alongside the study of books and valid and scientific global websites that discussing the idea of using new technologies along with the existing energy production. Using renewable energy, homes have been made from special materials, where the manner of design adjusts to the environment (like solar energy), but can still function in any condition. We have seen that by studying the available information, biogas and photovoltaic systems are also intended to (in addition to their own sufficiency) and lead to saving energy. The day is coming that single municipal buildings will manage to make their fossil energy usage reach zero.

Measuring “Fearonomic Effects” in Valuing Therapies: An Application to COVID-19 in China

ObjectivesTo develop a checklist that helps quantify the economic impact associated with fear of contagion and to illustrate how one might use the checklist by presenting a case study featuring China during the coronavirus disease 2019 (COVID-19) outbreak.MethodsBased on “fearonomic effects,” a qualitative framework that conceptualizes the direct and indirect economic effects caused by the fear of contagion, we created a checklist to facilitate empirical estimation. As a case study, we first identified relevant sectors affected by China’s lockdown policies implemented just before the Lunar New Year (LNY) week. To quantify the immediate impact, we then estimated the projected spending levels in 2020 in the absence of COVID-19 and compared these projections with actual spending during the LNY week. Data sources used include Chinese and global websites. To characterize uncertainty, we reported upper and lower bound estimates and calculated midpoints for each range.ResultsThe COVID-19 epidemic is estimated to cost China’s economy $283 billion ($196-369 billion), that is, ¥2.0 trillion renminbi (¥1.4-¥2.6 trillion), during the LNY week. Reduced restaurant and movie theater business ($106 [$103-$109] billion, 37.5% [36.4%-38.5%]) and reduced public transportation utilization ($96 [$13-$179] billion dollars, 33.9% [4.6%-63.3%]) explain most of this loss, followed by travel restrictions and the resulting loss of hotel business and tourism ($80.36 billion, 28.4%).ConclusionOur checklist can help quantify the immediate and near-term impact of COVID-19 on a country’s economy. It can also help researchers and policy makers consider the broader economic and social consequences when valuing future vaccines and treatments.

Detection of structure query language injection vulnerability in web driven database application

SummaryStructure Query Language Injection Attack is among the top 10‐security threats that can be used on the web application to cause severe damage or gain unauthorized data access to the application server. Many reports have indicated an average of 64% of global websites are at risk of being attack by SQL injection, and many of the top companies have experienced thousands of attacks attempts through SQL injection. The current trend shows the increasing number of attacks factor as a result of the daily deployment of these applications without security detection and prevention mechanism is placed. To overcome this challenge, researches in academia and industry presented a proposal that automates SQL injection vulnerabilities assessment on the tested application. Current studies show the need to enhance techniques of these proposals to reduce the false alarms. In this study, we propose a component‐based technique to minimize the incidence of inaccurate results, as well as enable the ease of improving the proposed solution. The study uses three costumed applications as tested to evaluate the accuracy of the proposed solution. Each of these testbed consists of several vulnerabilities where the experimental evaluation performs to test the proposed tool. An empirical evaluation is carried out on three vulnerable custom websites to evaluate the effectiveness of the proposed study. The experiment results indicated significant results in terms of high accuracy. On the other hand, the proposed solution also has better capabilities to analyze page response based on four different techniques. Moreover, the proposed solution is the only solution that performs stored procedure attacks SQL and bypass login authentication even if the returned records are limited restriction is applied.

Surface water map of China for 2015 (SWMC-2015) derived from Landsat 8 satellite imagery

ABSTRACTLarge-scale surface water mapping not only helps us protect, utilize and manage water resources but also contributes to the understanding of climate change and the hydrologic cycle. A recent study showed that a multilayer perceptron (MLP) neural network is an effective method to identify various surface water types from Landsat 8 Operational Land Imager (OLI) satellite imagery. We use this method to produce a surface water map of China for 2015 (SWMC-2015) at a 30 m pixel size. The accuracy of SWMC-2015 was assessed with a set of random water and not water validation points. The strengths and limitations of SWMC-2015 include: the SWMC-2015 clearly shows the major lake clusters and river networks with high mapping accuracy and the overall accuracy and kappa coefficients of SWMC-2015 are 90% and 0.78, respectively. The accuracy of SWMC-2015 can be improved from perspective of training samples representation, verification sample seasonal fluctuation and mixed pixel. The SWMC-2015 is available for free download on the remote sensing of global change website (https://vapd.gitlab.io/post/swmc2015/).

Health-related quality-of-life in patients with cholangiocarcinoma: Results of a systematic literature review.

e15623 Background: Cholangiocarcinoma (CCA) is a rare biliary tract cancer (BTC) with a historically poor prognosis and limited treatment options. Both quality and quantity of life can be important factors when deciding treatment, thus assessment of health-related quality-of-life (HRQoL) is needed to justify the use of novel therapies. HRQoL questionnaires are a standardized way to understand the patients’ perspective and treatment experience. The objective of this review was to examine the published literature specific to HRQoL in CCA. Methods: A systematic literature search was conducted using EMBASE and MEDLINE from Jan 2008 to June 2018 to identify abstracts with published HRQoL data in CCA patients. This review also included global conference proceedings (2015-2018) and HTA websites. Articles were considered relevant if they reported HRQoL data in patients with CCA, bile duct carcinoma, and/or hepatobiliary system cancer. Results: Of the 2,933 studies initially identified, 7 ongoing or completed studies met the scoping criteria to be included in the review. No articles in this literature review reported data from clinical trials. Multiple HRQoL measures were utilized; however within the studies, EORTC QLQ-BIL21 was the only HRQoL measure developed and validated specifically for BTC (CCA, gallbladder, or ampulla vater) identified in this review. 3/7 studies included information on CCA subtypes (intrahepatic, extrahepatic) with 2/3 studies reporting HRQoL by subtype. Patient symptoms were reported in 4/7 studies, including gastrointestinal distress, abdominal pain, fatigue, fever, itching, difficulty sleeping, anxiety, jaundice and weight loss. Conclusions: Within this literature review, few studies have been published with HRQoL data in CCA patients. Data from the existing published literature is generally from a heterogeneous patient population, and not consistently specified for CCA stage or subtype. To better understand HRQoL in CCA patients, more data needs to be generated that include clinical trials for novel therapies.
